     Pre flight checks

Pre-flight checks must be undertaken before every flight to ensure it can be carried out safely and without incident. A copy of the pre-flight check list can be found on the outer sleeve of the Rofalcon Box.


  • Does the motor look, sound and feel like it is running well?
  • Have you accidently run the engine for a moment when it was stuck in mud or sand?
  • Is the fan clean and spinning freely?
  • Are the edges of the fan blades becoming worn?
  • Is a blade loose or missing? If so, replace the fan.
  • Is the engine securely in place and in proper alignment?
  • If it has shifted forward, put hot glue under the rim and push it back into line.


  • Check the battery is fully charged using a voltmeter.
  • Is the battery puffed, swollen or damaged in any way?
  • Old or weak batteries can greatly decrease power and shorten the flight time.
  • Have you used an empty battery instead of a new battery by mistake?


  • Is the transmitter charged?
  • Is the receiver bound to the transmitter?
  • If not: Turn the transmitter on, turn the model on. Press and hold the little black button on the back of the receiver for 3 seconds. Then turn everything off and on again.
  • Are all electrical connectors tight, secure and in good repair?
  • Is the stabiliser exactly horizontal and secure?
  • Does each control give the right response from the model?


  • Do the servos move smoothly without grinding?
  • Do the servos give the right amount of movement on the flight surfaces?
  • Is the reflex trimmed properly with the elevons slightly up?
  • Are the servo wires in good repair and well-secured?


  • Is there any structural damage to the model that needs to be repaired?
  • Is the rubber band secured and still strong enough for hard flying?
  • If the rubber band is weak, you will see wing flutter during hard manoeuvres.
  • Are all of the horns on the surfaces intact and well secured?
  • Is there smooth airflow over all wing surfaces?
  • If any fluttery feathers are added they must be on the head or trailing behind, but NOT on the wing.
  • Are all repairs strong, smooth and correctly aligned without adding weight?
  • The all up weight should not exceed 650g.
  • Did you hold the fuselage level when connecting the battery, until the stabiliser established?
  • Have you checked that the stabiliser is working by tilting the model?


  • Do you need some help to fly this type of model?
  • Have you spent time on a buddy cord or simulator with a similar model?
  • Do you have a qualified trainer who knows what they are doing?
  • Do you understand what they are telling you?
  • Do you know how to launch your model properly?
  • Can you handle a radio controller in one hand while you launch the model with the other?
  • Having an assistant to launch the model in the early stages can be very helpful.


Go through this checklist before you fly, and go through it again after any accident or model modification.
